ABSTRACT:
A system for significantly reducing the dissolved oxygen content of a liquid. Liquid is pumped from a supply source to a deoxygenation chamber through a line containing a sparger for injecting a gas, such as nitrogen, as bubbles having an average size of not greater than about 5 mm. The sparger is spaced a predetermined distance upstream of the chamber to achieve contact at the bubble interface for a desired length of time. The pressure of the liquid is lowered when it reaches the chamber, releasing the nitrogen bubbles which are vented to the atmosphere along with the oxygen stripped from the liquid. The dissolved oxygen content of said liquid can be monitored at a location upstream of the sparger, and adjustments made to the amount of nitrogen being injected based upon the D. O. level monitored.
